The formula for electric field strength is 'E = F/Q', where E is electric field strength and F is force and Q is the charge. Which one of the following options gives the correct base units for electric field strength?
Correct answer: A. kg m s-3 A-1
- A. kg m s-3 A-1
- B. kg s-2 A-3
- C. kg2 m-2 s-3 A
- D. m s-1 A-3
Explanation
Force-mass x acceleration-kg x ms-2.Q=current(1) x time(t)=IT=A.sE=F/Q-kg ms-2/As .E=kgms-3A-1As it is a numerical, it can have only one possible answer.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
